What if the computer can't be turned on in cold weather?

Take Lenovo G40-70 and win 10 systems as examples. In winter, the computer can't be turned on because of the low temperature;

1. The temperature of the computer case is too low, so the computer can't be started normally. You can turn on the heat source to adjust the indoor temperature, or you can turn on the chassis to preheat the motherboard with a hair dryer. This method needs to pay attention to safety or operate under the guidance of professionals to prevent potential safety hazards.

2. Unstable power supply will also cause the computer to fail to boot. You can plug in the computer, power on the motherboard, and wait for about 30 minutes before turning it on.

This answer applies to some Lenovo models.

When the external environment is too low, the computer will expand with heat and contract with cold. When the solder joints between components and circuit boards expand with heat and contract with cold, there will be cracks or poor contact. Starting a computer in cold weather requires an adaptation process or changing the external environment. Therefore, the indoor standard temperature range should be kept between 22 2℃ in summer and 65438 06 2℃ in winter. Generally, the ambient temperature is 19 to 22℃. When the temperature is lower than 5℃ or higher than 35℃, the computer can't start normally.
